EDWARD WESTON, OF NEWARK, NEW JERSEY, ASSIGNOR TO THE UNITED STATES ELECTRIC LIGHTING COMPANY, OF NEW YORK, N. Y.

lNCANDESCENT-LAMP HOLDER.

SPECIFICATION forming part of Letters Patent No. 268,329, dated November 28,1882.

Application filed August 28, 1882. (No model.)

To all whom it may concern:

Be it known that I, EDWARD WESTON, a subject ot'theQueen ofGreat Britain. and a resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful lmprovementsin Incandescent- Lamp Holders, of which thcfollowingis a specification, reference being had to the drawings accompanying and forming a part ot'the same.

My invention consists in the combination, with a socket-forincandescent lamps, ofa noyel device for holding the lamp in position and completing the circuit through the same, the character and arrangement of these devices being illustrated in the accompanying drawings, in which- Figure 1 is a view of a lamp and socket or holder-combined, the latter being shown in section. Fig.2is a sectional view ofthesocket alone, taken at right angles to that of Fig. l.

A is an ordinary cup-shaped socket ot' insulating material, arranged forattachment to a gas or similar bracket.

in the upper part of the socket A are cut vertical slots B.

In the bottom of the socket are secured two small screw-posts, O O, and to the ends of these, projecting up through the base of the socket, are connected spiral springs D D. The upper ends of these springs pass through a piece, E, of insulating material, and are bent over to form hooks, e. Pins d, inserted in the edge of the piece E, extend through the slots B. The

' shape of the piece E is by preference that of a flat round plate, though this is of course arbitrary. The cup or socket, too, may be varied in appearance, as by being formed ofopenwork, or given any one of a variety of shapes.

To use a lamp with this holder, the conducting-wires F F, at or near the points where they leave the glass, are bent around into eyesff, or these eyes or their equivalents may be secured to the wires or otherwise formed, as will be readily understood. When the lamp is to be inserted in thesocket the plate E is raised by means of the pins 01 until the hooks c 6 appear above the edge of the socket. Thela-mp is then connected to them by means of the eyes f fand the pins d set free. The force of the springs drawing down on the lamp will hold it firmly in position, and if the posts be connected with the wires of a circuit the lamp' will complete the circuit, good contact being assured by the action of the springs.

An advantage results from the use of the plate E, which, in the existing forms of socketcontaining springs, is not found, in that the with the corresponding eyes or hooksff, on the lamp, so that to secure a lamp to the holder occupies but an instant.

A further advantage results from the slotted socket in this particular type of holder, as by means of it the retaining-springs or equivalent devices within the socket may be brought up and hooked to the lamp with greater facility than if it were necessary to draw them up by means of some instrument inserted into the socket from above.

I do not claim herein, broadly, a socket containing spiral springs for holding in a lamp; but

W hat 1 claim is- 1. A holder t'orincandescent lamps, consist ing of a cup or socket, in combination with hooked spiral conducting-wires secured in the bottom of the same, and apiece or plate of in sulating material, by which the spirals are held in position for engaging with the conductors ofa lamp, as set forth.

2. In a holder for incandescent lamps, the combination, with a vertically-slotted socket or cup, 0t hooked spiral conductors secured in the bottom of the same, a piece orplate ot' insulating material, by which the spirals are held in place, and pins or projections from the plate extending through the slot, as and for the purpose set forth.

3. A socket or holder consisting of an insulating socket or cup, spiral conducting-wires secured in the bottom of the same, and a piece or plate of insulating material, through which the free ends of the spirals are passed, in combination with an incandescent lamp having conducting-wiresformed'or provided with eyes for engagement with the wires of the socket, substantially as described.

In testimony whereot'l havehereunto set my hand this 21st day of August, 1882.

EDWARD WESTON.
